Chosen Solution
Not sure what happened. Installed a new battery with no issues however no sound is heard while making calls. Speaker works just fine.
· Did you remove the screen while replacing the battery? · If you record a voice memo can you hear it through the ear piece speaker? · Is your front camera working correctly? If you could here on calls before you replaced the battery and you removed the screen while doing so it would point to the front camera flex assembly. Check if the connector is seated properly into the connector.
